Citric acid production by solid state fermentation using sugarcane bagasse
Abstract A solid state fermentation (SSF) method was used to produce citric acid by Aspergillus niger DS 1 using sugarcane bagasse as a carrier and sucrose or molasses based medium as a moistening… Expand
Continuous metal removal from solution and industrial effluents using Spirogyra biomass-packed column reactor.
The granule-packed column could efficiently remove different metals from real industrial effluents, and hence the test biomass (Spirogyra granules) is a good candidate for commercial application. Expand
Kinetic and isotherm modeling of lead(II) sorption onto some waste plant materials
Abstract Peepul leaves were identified as the most potent Pb(II) sorbent ( q max = 127.34 mg g −1 ), followed in decreasing order by banana peels (72.79 mg g −1 ), peanut hulls (69.75 mg g −1 ),… Expand
Metal sorption by algal biomass: From batch to continuous system
Abstract Algal biomass possesses tremendous metal binding ability and therefore has great potential for gleaning these pollutants from wastewaters. The algal cell wall and exopolymers contain diverse… Expand
Chemical reaction- and particle diffusion-based kinetic modeling of metal biosorption by a Phormidium sp.-dominated cyanobacterial mat.
The diffusion-based models, namely, the intra-particle diffusion model and the external mass transfer model fitted well to the time-course metal sorption data, thus suggesting involvement of both external and intra- particle diffusion processes in sorption of test metals by mat biomass. Expand
Copper(II) and lead(II) sorption from aqueous solution by non-living Spirogyra neglecta.
During repeated sorption/desorption cycles, Pb(II) and Cu( II) sorption decreased by 11% and 27%, respectively, at the end of the fifth cycle due inter alia to 10-15% loss of biomass. Expand
Mono-component versus binary isotherm models for Cu(II) and Pb(II) sorption from binary metal solution by the green alga Pithophora oedogonia.
The sorption of Cu(II) and Pb(II) by Pithophora markedly decreased as the concentration of the secondary metal ion, Cu(II) or Pb(II), increased in the binary metal solution. However, the test alga… Expand
Morphological abnormalities in periphytic diatoms as a tool for biomonitoring of heavy metal pollution in a river
The utility of morphological abnormalities in diatom frustules as an effective tool for biomonitoring of heavy metal pollution in waterbodies is shown. Expand

A good mechanical strength of Pithophora biomass was apparent as only 10-15% loss of biomass occurred at the end of the fifth cycle, and the regenerated biomass of Pityophora has better reusability for Pb(II) than for Cu(II). Expand
Effect of thermal and thermosonication on anthocyanin stability in jamun (Eugenia jambolana) fruit juice
- C. A. Shaheer, P. Hafeeda, R. Kumar, T. Kathiravan, Dhananjay Kumar, S. Nadanasabapathi
The purpose of this investigation is to study the influence of high intensity ultrasound, sterilization and pasteurization on the stability of anthocyanin in jamun fruit juice. Different ultrasound… Expand
